Triss [41]

Answer:

The value of polynomial for x = 2 that is f(2)  will be 32  

Step-by-step explanation:

We have given polynomial f(x)=3x^2+8x+4

We have to find the value of f(2)

We have to find the value of polynomial for x = 2

So for finding this value we have to just put x = 2 in polynomial

So f(2) will be f(2)=3\times 2^2+8\times 2+4=32

So the value of polynomial for x = 2 will be 32
